About This Game

A World of Mollusks Awaits

Dive into the fascinating world of mollusks — from humble garden snails to majestic octopuses. Discover and collect

over 500 hand-drawn species across 9 themed packs, each with unique movement and behavior.

9 Diverse Packs to Explore

- Garden & Forest — Watch snails slowly crawl across mossy terrain

- Beach & Tidepool — Limpets and conchs cling to sun-warmed rocks

- Freshwater — Peaceful pond snails drift through calm waters

- Coral Reef — Nudibranchs glide gracefully among vibrant corals

- Spiral Shells — Heavy-shelled beauties crawl along the ocean floor

- Bivalves — Oysters and mussels rhythmically open and close their shells

- Hunters — Cone snails and predators stalk their prey

- Cephalopods — Octopuses and squid jet through open water

- Deep Blue — Mysterious creatures drift in the eternal dark

Real-Time Growth

Every mollusk starts as a tiny larva. Watch them feed, grow, and undergo metamorphosis into their adult forms — each

with distinct poses and behaviors. Land snails crawl, bivalves anchor to the seafloor, and cephalopods burst through

the water with jet propulsion.

Idle & Relaxing

Your habitats thrive even while you're away. Come back to find your mollusks have grown, earned income, and discovered

new behaviors. Gentle ambient sounds and hand-drawn art make Molluscarium the perfect background companion.

Customize Your Habitats

Design the perfect environment with upgradable backgrounds. Watch your creatures interact with their surroundings —

bottom-dwellers hug the substrate while swimmers explore every corner.

Collect Rare Variants

Each species can appear in four visual variants — Normal, Painted, Golden, and Rainbow. Hunt for the rarest

combinations across seven rarity tiers from Common to Ancient.
